Comment 1 Markku Korkeala 2026-07-29 12:12:34 UTC

Thanks you for the bug report. I can replicate the issue in Fedora 44, does not seem to happend in Fedora 43.

It seems build of spec.alpha is not compatible with the rest, if I download that from maven central (https://repo1.maven.org/maven2/org/clojure/spec.alpha/0.6.249/ ) and run it repl starts:

java -cp /usr/share/java/clojure/clojure.jar:/usr/share/java/clojure-core-specs-alpha/core.specs.alpha.jar:spec.alpha-0.6.249.jar clojure.main

But with the jar in fedora, it fails:
java -cp /usr/share/java/clojure/clojure.jar:/usr/share/java/clojure-core-specs-alpha/core.specs.alpha.jar:/usr/share/java/clojure-spec-alpha/spec.alpha.jar clojure.main

Have to dig little deeper where is the fault.

Comment 2 Markku Korkeala 2026-07-29 12:27:55 UTC

I did a new scratch build for spec.alpha ( https://koji.fedoraproject.org/koji/taskinfo?taskID=148447380 ), could you try if this fixes your issue?

Download the package: $ wget https://kojipkgs.fedoraproject.org//work/tasks/7380/148447380/clojure-spec-alpha-0.6.249-1.fc44.noarch.rpm
Install the package: $ sudo rpm -U --force clojure-spec-alpha-0.6.249-1.fc44.noarch.rpm
Try again to run clojure: $ clojure

You can always try those in toolbox/distrobox/other container, if you do not want to run rpm -U --force on your system.

Comment 3 Osmani Rosado 2026-07-29 15:28:28 UTC

Thanks for your help. It works using the scratch build you provided:
